* mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

Browse Source 
mips_skip_stub, mips_ignore_helper): New functions for dealing
	with MIPS16 call/return thunks.
	(mips_init_frame_pc_first): New function to implement
	INIT_FRAME_PC_FIRST macro; includes code from old macro plus
	new code to skip over MIPS16 thunks.
	(mips_frame_chain): Skip over MIPS16 thunks.
	* config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
	mips_skip_stub, mips_ignore_helper): Declare.
	(IN_SOLIB_CALL_TRAMPOLINE, IN_SOLIB_RETURN_TRAMPOLINE,
	SKIP_TRAMPOLINE_CODE, IGNORE_HELPER_CALL): New macros that invoke
	the above functions.
	(INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
	(mips_init_frame_pc): Declare.
	* infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
	to decide if certain library function calls should be ignored.
